CATTLE-GUARD.

Specification of Letters Patent.

Patented Oct. 1,1912.

Application filed February 13, 1912. Serial No. 677,359.

To all whom it may concern:

Be it known that I, CIoEno A. FEWELL, a citizen of the United States,residing at Glenwood, in the county ofPike and State of Arkansas, haveinvented certain new and useful Improvements in Cattle-Guards; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in cattle guardsfor railways and provides a simple and efficient means so arranged thatthe weight of an animal coming upon the apparatus will'cause a fence orobstruction to be raised to arrest its further progress, the partsreturning to their normal positions after the weight has been removedfrom the apparatus.

The invention comprises various details of construction and combinationsand arrangements of parts which will be hereinafter fully described,shown in the accompanying drawings and then specifically defined in theappended claim.

I illustrate my invention in the accompanying drawings, in which Figure1 is a top plan view showing the application of the invention, and Fig.2 is a sectional view on line 22 of Fig. 1.

Reference now being had to the details of the drawings by letter, A, Adesignate the usual tracks of a railway, and pivotally mounted upon theposts B are the hangers C, the lower ends of which are pivotal'lyconnected to a shaft D upon which the outer end of the platform E ispivoted, the forward end carrying a shaft or rod F mounted in a roll Eformed at one edge of the plat form. Posts H have pivotally mountedtherein a shaft I upon which a swinging gate 0 is journaled, which gatehas forwardly projecting portions Q which are j ournaled upon the shaftPosts N have pivotal pins N fixed thereto upon which the levers T arepivoted and which are pivotally connected to the links K which in turnare pivotally connected to the shaft F, and each of the levers T has aweight It adjustably mounted thereon. The

weights B have set screws R mounted therein, serving as means wherebythe weights may be held in adjusted positions upon the lever. It will benoted that the gate 0 is provided with serrations 0 upon one edge which,when the gate is thrown to an upright position, will serve to assist inarresting further progress of an animal which might make an attempt topass by the cattle guard.

In operation, it will be noted that the counterbalanced weights willserve to hold the parts as shown in solid lines in Fig. 2 of thedrawings, in which the gate will be below the plane of the tread surfaceof the rails. W hen an animal attempts to pass between the posts B andstepping upon the platform will cause the latter to be depressed andassume the position shown in dotted lines in Fig. 2, which will causethe gate to be thrown to an upright position. After the weight isremoved from the platform, the parts will return to their normalpositions through the medium of the counterbalance weights.

What I claim to be new is A cattle guard comprising oppositely disposedposts, hangers having angled ends pivotally mounted in said posts, ashaft adapted to be supported by the hangers beneath the rails of therailway, a platform resting at one edge upon said shaft, pivotalweighted levers, posts upon which the same are mounted, the edge of saidplatform opposite the one supported by said shaft being recessed, ashaft j ournaled in projections upon therecessed edge of the platform,links connecting the ends of said shaft which is carried by the platformwith the ends of said weighted levers, a tilting gate and shaft uponwhich the same is mounted, said gate having lateral projections upon oneedge which are pivotally connected to the shaft mounted upon therecessed edge of the platform, said gate being recessed to allowportions thereof to swing on either side of the tracks, as set forth.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.

GIGERO ALEXANDER FEWELL.
